REVOLVING SPRAYER Filed Sept. 6, 1945 2 Sheets-Sheet 2 b a a /9 X 5/ I m'culor Attorneys 6 207 96 iiaizapz'n Application September This invention relates to a spraying apparatus and especially to one that will spray foliage of any sort and from any angle.

An object of the present invention is to provide a spraying device of durable and inexpensive construction with simple mechanism for regulating the area to which the spray may be directed.

Another object is to provide a nozzle for such spraying that may easily be adjusted so that the circumference or width of the spray may be varied to any desired degree.

Another object is the provision of a sprayer that may be adjusted so that the spray may be confined to a small area, such as small bushes, or, expanded to cover a large area, such as fruit trees or even larger trees. I

Another object is to provide an automatic means, after the mechanism has once been set, to deliver the spray in any one of the desired arcs.

With these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the above and other objects are obtained, as hereinafter more fully set forth, pointed out in the claim and illustrated in the accompanying drawings, in which:

Figure 1 is a general view showing the operation of the sprayer;

Figure 2 is a sectional view illustrating the means for revolving the nozzle;

Figure 3 is an elevation of the socket plate, taken on the line 3-3 of Fig. 2;

Figure 4 is a sectional detailed view of the nozzle taken on the line 4-4 of Fig. 2, and

Figure 5 is a view showing the nozzle and swivel joint, taken on the line 55 of Fig. 2.

In the accompanying drawings the numeral It) indicates the entire spraying apparatus having the spray receptacle ll mounted on the wheels l2 and I3. The motive power l4 may be of any conventional type and be arranged to rotate the pulley or gear wheel l5 which is keyed to a shaft 16 which is supported in a bearing of i the standard [1. Rigidly affixed to the other end of the shaft I6 is a socket plate 53 having a plurality of sockets l8, I9, 20 and 2| (see Fig. 3) therein.

The nozzle 22 is supported by the yoke 23 in the outer portion 24 of the standard I1. At the upper end of the portion 24 there is preferably provided a recess 25 arranged for rotatable reception of the screw bolt 25 which is held in place by means of the nut 21 at its lower end and the flange 28 at its upper end, said flange being adjacent the fork members 23 and 30. These fork members have at their upper ends the bearings REVOLVING George R. Chapin, 1'

s, missus... 614,708: '1 can. (Cristi-ta stunts 3': "an at "and {positioned ma lman the sh fts 33;; 3 4,: the shafits -being threaded into the boss s 35 and 38 of the tubular portion 31 of the nozzle 22.

There are preferably provided two spray feeding hoses 4| and 42 and they may be arranged in any conventional manner, as indicated at 43 and 44, to allow rotation of the shafts 33 and 34 while at the same time not permitting leakage of the fluid.

Threaded into the outer end of the tube 31 is an elongated member 45 having threaded at its outer end the flared spray opening 46 with an opening 4'! therein which may have its outlet capacity and shape of spray regulated by inward or outward movement of the head 48 of the bolt 49. This bolt extends inwardly through the elongated member 45 and the tube 31 and is threadably disposed in the head 50 of the actuating rod 5|. The head of the rod 5| is threaded into the tube 31 while on its inner end it carries a ball 52 which is loosely received by any of the sockets I8, l9, 2| or 2| of the rotatable socket plate 53.

The sockets in the plate 53 may be of any number desired, but for the purpose of illustration I have shown four such sockets. It will be seen by reference to Fig. 3 that these sockets vary in distance from the center of the plate 53, the closest one thereof being 2|, hence movement thereof will afiord the least movement to the outer end of the nozzle, while the one furtherest away from the center, that is [8, will give a maximum of movement to the outer end of the nozzle, when the ball 52 is disposed therein.

The rotation of the socket plate 53 will give a corresponding rotating movement to the ball which will cause a rotating movement of the spray head 46 due to the universal mounting of tube 31, afforded by the swivel mounting of the yoke 23 and trunnion block 33, 34, the pivots of which have their axes disposed at right angles to one another.

The invention thus renders an action of adjustable spray both as to spread or deflection and contour of the spray; that is, a circular or spiral direction of the spray and an adjustable means for the entire area of the spraying action.

Obviously as the nozzle rotates in response to the plate 53 and while the vehicle is traveling, a rotating progressive effect and application of the solution to the trees is accomplished in an efficient and thorough manner.

While the foregoing description sets forth the preferred embodiment of my invention in specific terms illustrated by the accompanying drawing, it is to be understood that numerous changes or modifications in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

I claim:

In a spraying device, a nozzle mounted intermediate of its ends for universal swinging movement, af driven rotary shaft, a socket platesecured to the shaft and rotatable therewith, the

plane of the socket plate being at a right angle,.

to the axis of the shaft, said nozzle having an outer discharge end and an opposite inner endprovided with a ball, and a socket in saidsocket plate in which the ball is swivelly disposed,'said socket being spaced radially fromthe' axis of the shaft and being revolved by the shaft int.

predetermined circle around the axis of the shaft for revolving each of the ends of the nozzle in a go 7 circle'of a predetermineddiameter:
